The Reflection Of The Hippocampus And Memory Function

“Information flows from the outside world through our sight, hearing smelling, tasting and touch sensors. Memory is simply ways we store and recall things we 've sensed.” When we recall memories, the original neuron path that we used to sense the experience that we are recalling is refined, and the connection is made stronger. Sensory information in stored for only a few seconds in the cortex of the brain. This information can then progress to short-term memory, and then long-term memory, depending on the importance of the information received.

* Tip- of-the-tongue phenomenon- when you know certain information but have difficulty being able to recall it.

Memory is the process of encoding, storing and retrieving information in the brain. It plays an import role in our daily life. Without memory, we cannot reserve past experience, learn new things and plan for the future. Human memory is usually analogous to computer memory. While unlike computer memory, human memory is a cognitive system. It does not encode and store everything correctly as we want. As suggested by Zimbardo, Johnson and Weber (2006), human memory takes information and selectively converts it into meaningful patterns. When remembering, we reconstruct the incident as we think it was (p. 263). Sometimes our memory performance is incredibly accurate and reliable. But errors and mistakes are more commonly happen, because we do

Memory refers to the persistence of learning in a state that can be revealed at a later time (Squire, 1987). A memory is a network of neocortical neurons and the connections that link them. That network is formed by experience as a result of the concurrent activation of neuronal ensembles that

“Alzheimer's disease is a progressive, degenerative disorder that attacks the brain's nerve cells, or neurons, resulting in loss of memory, thinking and language skills, and behavioral changes. These neurons, which produce the brain chemical, or neurotransmitter, acetylcholine, break connections with other nerve cells and ultimately die. For example, short-term memory fails when Alzheimer's disease first destroys nerve cells in the hippocampus” (Alzheimer’s Association Foundation.) The destruction of the hippocampus is very serious because the hippocampus is a structure in the brain’s limbic system that plays an important part role in memory (Ettinger 91.) Its is responsible for forming organizing and storing memories.It connects the memories to structures and senses like smell and sound. “The hippocampus is a horseshoe shaped paired structure, with one hippocampus located in the left brain hemisphere and the other in the right hemisphere. The hippocampus acts as a

Memory is a set of cognitive processes that allow us to remember past information (retrospective memory) and future obligations (prospective memory) so we can navigate our lives. The strength of our memory can be influenced by the connections we make through different cognitive faculties as well as by the amount of time we spend devoting to learning specific material across different points in time. New memories are created every time we remember specific event, which results in retrospective memories changing over time. Memory recall can be affected retrospectively such as seeing increased recall in the presence of contextual cues or false recall of information following leading questions. Memory also includes the process

Since it is close structurally to the hippocampus, the amygdala is involved in controlling memory consolidation, especially emotional memories; when a memory is emotionally charged, it has a better retention rate than one that is not. The hippocampus is generally seen as having an essential role in the creation of new memories about past experiences; it's even responsible for memories that can be verbalized also known as declarative memory. Damage to it result in difficulties in forming new memories and being able to access new memories formed before the

Some scientists believe that parts of long term memory are permanent while others will eventually weaken over time. (3) Long term memory can be divided into three sections: procedural memory, declarative memory, and remote memory. Procedural memory includes motor skills such as learning how to ride a bike or how to drive a car. "Such memories are slow to acquire but more resistant to change or loss." (4) Declarative memory is used to remember facts, such as names, dates and places. It is easy to learn but also easy to lose. Finally there is episodic memory, which is the record of events that a person stores throughout his or her experience. Recent studies show that these events, as soon as they occur, are sent to a temporary part of the brain called the hippocampus, and that over time they are moved to the neocortex for permanent storage. (5).

Doctors and scientists dispute the exact role of the hippocampus, but agree that it has an essential role in the formation of new memories about personally experienced events. Some researchers prefer to consider the hippocampus as part of a larger medial temporal lobe memory system responsible for declarative memory. When a long-term, declarative memory is made, certain neuronal connections in the temporal lobe are strengthened, and others are weakened. These changes are fairly permanent, however some may take weeks or months before they are complete

The hippocampus assumes an essential part in our recollections. It appends recollections to the feelings and faculties that run with them. For example, it will take a memory of being cheerful and quiet while in a field and connection it with the possess a scent reminiscent of the blossoms. It will relate both the sentiment being upbeat and the feeling of smell to the memory of being in a field.

There are two different types of memory; individual and collective. Individual memory is defined in the article “Individual and Collective Memory” written by Sara Hanneman and Brianna Brandon, as “a

The brain is the most important organ, and any animal, even mosquitoes have them. However, have you thought any special ability of the brain, or have you imagined about your personality, emotion or memory in the situation which you lost a part of brain? In fact, there are lots of great abilities such as memory in the brain without our notice. Although, all the brain’s tasks are not clear completely, a lot of scientists have researched it and found its several miraculous functions (Newhouse 2007). The brain consists of many parts; particularly, this paper describes four parts of the brain which relate to memories or emotions. People who lost those four parts or a part of those would get effects on their memories

There are many types of memory, but broken into two general types; short term and long term. Short term according to animal studies is said to be electric signals moving in circuits through series of neurons. When information is put into long term memory it is maintained in a certain type of protein. All of this of course happens in a matter of seconds, but it is still a complex process just to realize, for example, that the stop light is red and then to know to step on the brake and slow down (How Does the Brain Process Information? 1999).

(1). Therefore, once one sees something else or takes part in a new conversation is it difficult to remember all of the details from the one before. Declarative memory includes remembering facts one has used effort to learn in the past, and things one has tried to remember. The last part of memory, procedural memory, consists of everything one has learned by repetition, such as playing an instrument or sport, driving a car, or walking.

C. In general, the brain's system for creating and using memories is very effective, but problems often occur.
